Description
Technical field
The utility model belongs to coke oven auxiliary facility technical field, specifically is a kind of dust and fume control equipment that pushes up when adorning coke oven coal-charging.
Background technology
In the prior art, push up the dedusting of dress coke oven coal-charging and mainly contain three kinds of modes: the flue dust that (1) utilizes blower fan and pipeline to produce when the coal port suction is coaling, utilize the cleaning apparatus that is located on ground or the coal charger that the flue dust that aspirates is purified again.This mode is suitable for various tops dress coke oven, but facility investment is big, the process cost height; (2) utilize high pressure aqua ammonia that the flue dust that the current coking chamber of coalingging produces is drawn into the effuser from upcast.This mode is suitable for various tops dress coke oven, but dust removing effects is poor, still has volume of smoke to overflow from the hole of coalingging; (3) utilize leap pipe and little upcast with current coking chamber of coalingging (n coking chamber) and n+1 coking chamber UNICOM, the flue dust that produces when the n coking chamber is coaling is drawn into the effuser from the upcast of n coking chamber and n+1 coking chamber.This mode mainly is suitable for the coke oven of 2-1 coke pushing string preface, and needs to establish special-purpose little upcast at each coking chamber, and the flue gas that is extracted into the n+1 coking chamber from the n coking chamber does not burn during crossing over pipe, crosses over Guan Yi and is stopped up by carbon distribution, influences dust removing effects.
Summary of the invention
The utility model has solved coaling flue dust that suction force that process effusion raw gas utilizes high pressure aqua ammonia produces when coalingging from two coking chambers of coke furnace carbonization chamber and has aspirated the technical problem of improvement, provide a kind of simple in structure, investment is low, process cost is low, the smokeless coaling gear of double suction combustion-type of good dedusting effect.
The utility model is to realize like this, the smokeless coaling gear of double suction combustion-type, it is characterized in that coalingging the dust collecting cover wound packages at coal charger each bucket level of coalingging coaling below the flashboard, the control of dust telescopic external fixation sleeve of respectively coalingging gathers pipe with flue gas collection tube, flue gas and links to each other, link to each other with the flue gas delivery line again, the lower end of flue gas delivery line is connected with flue gas and derives sleeve, and flue gas is derived sleeve and just is positioned at coking chamber at coal on the hole of coalingging of No. 1 coking chamber.Flue gas is derived sleeve and is positioned on the hole of coalingging of n+2 coking chamber.N is the coking chamber of coalingging number, and it is quill that flue gas is derived sleeve, and adopts same hoisting appliance with two, three layers of quill of control of dust telescopic, with the control of dust sleeve lifting simultaneously of coalingging; Flue gas is being coaling control of dust sleeve and be attached thereto the pipeline internal combustion that connects, and gas fume after burning enters the n+2 coking chamber through the flue gas delivery line, has eliminated the raw gas loss.
Coaling control of dust telescopic external fixation sleeve and internal layer fixed muffle described in the utility model are fixed on the bucket flashboard below of coalingging together, and outer quill links to each other with hoisting appliance, on the outer wall of internal layer quill clamp is housed, and links to each other with outer quill; Take semitight between its China and foreign countries quill and furnace roof, the internal layer quill stretches in the hole of coalingging of n coking chamber, and and charging hole seat between do not take seal approach.Semitight state between outer quill and the furnace roof face can guarantee to burn with flue gas in enough air admission pipelines, can guarantee the suitable and unlikely generation blast of the air capacity that enters again; Form flue gas between the inside and outside layer quill and derive passage, flue gas is imported combustion chamber between the inside and outside fixed muffle.
Be provided with labyrinth seal between external fixation sleeve described in the utility model and the outer quill, avoid the flue dust loss, realize the cleaner production of coke oven.
The smokeless coaling gear of double suction combustion-type described in the utility model is characterized in that flue gas collection tube and flue gas gather pipe and be provided with clean-out opening, prevents line clogging.
It is 1.5-1.7m with the distance that coke oven pushes up that the utility model flue gas gathers pipe, is convenient to pass through.
Simple in structure, advantages such as expense is low, good dedusting effect that the utility model compared with prior art has, the effusion raw gas imports the n+2 coking chamber again after system's internal combustion, can not cause the obstruction of system and pipeline, and flue dust collecting is effective.
